"Harry might have taken Taylor's swipes with an air of grace, but he now wishes he never ever dated her," a friend apparently told RadarOnline. "I mean, the fact she's aiming a jab at him in the 22 video has got Harry wondering what's coming next! He just doesn't know what to expect.

They continued: "It wasn't the most amicable of splits, but Harry said all along that he wanted to take things slow and easy with Taylor."

The friend added that the reason Harry has kept so silent on the split is out of respect and he feels a more "grown-up person"

"What for Harry was 'a bit of fun' at the time has slowly turned into a personal nightmare," they added. "But he won't stoop to Taylor's level, he's just going to continue to be the more grown-up person and get on with his life. Perhaps something Taylor should consider too."

Meanwhile, Harry was recently linked with dating a Megan Fox lookalike he met at one of the group's shows in Belfast – something which has since been downplayed.
